zfl'zzeas 6's Eva/2Z0? i jaiizldz Coil/ means or a s iral spring 1' through an adjusting screw 5, and consequently, since it is held by friction, it takes part in. the movements of the carriage j.

The hooks o, 0 are hoth secured to a lever w which, by iineans of a slide it, can be oscillatedv by the cam a on the shaft (1, in order to insert the hooks 0, 0 into the eyes of the needles, the lever to being provided with a slot in the resent instance to receive a pin 4; on the sli e a, whereby reciprocation of the latter serves to automatically move the thread engaging hooks to and from operative position. in order to enable the two hooks to enter at the same time into the eyes of the needles, for the purpose of engaging the ends of the gathering or shirring thread, either the upper book i) is suitably bent (Figs. 2.

and 3)or the eyes of the needles are made sufficiently large to enable the two hooks to pass through the eye of the front needle (Fig. 4 y

The separate p arts 2, 2 of the middle 1nemher of the folding device operate with the actuating levers of the outer folding jaws 'm, m in the manner herein described so that,

during the inward motion of these jaws of the outer folding member, the jaws z, z of the inner folding members are sunultanc-- 'ously moved outwards in opposite directions,

so that the relatively displaced teeth of the outer crimping or folding jaws enter the spaces and fold the material .(shown dotted in Figs. 6 and '7 By this means, the pins 8 (see Figs. 5 and 6) on the parts 2, 2 at the same time serve to support the tubular fabric when applied. over the inner jaws. if desired, the parts 2, 2 can be fixed in their drawn out positions (Fig. 7), so that only the outer crimping or folding jaws m, to require to be moved, the parts 2, z in this in stance bcing\supported rigidly in staggered or zigzag r lation corresponding to the position occupied during the crimping or folding operation by these parts or inner jaws when movable.

1. An apparatus for crimping or folding the ends of tubular textile fabric and for drawing a gathering or shirring thread into the crimped or folded part of said fabric, said machine emnprising means for supporting and crimping said fabric, needles, a movable carriage for said needles, means for moving said carriage, thread-carryiug hooks adapted to en tor the eyes of said needles, a single carriage bearing both of said hooks and means for moving said carriage transversely to said needles.

2. An apparatus for crimping or folding the ends of tubular tcxlilc fabric and for drawing a gathering or shirriug thread into the crimpcd or folded part of said fabric, said machine comprising means for supporting and crimping said fabric, needles, a movable carriage for sald needles, means for moving said carriage, thread-carrying hooks adapted to enter the eyes of said needles, a lever hearing both of said hooks, and means for oscillating said lever so as to move said hooks into and out of the eyes of said needles, substantially as described.

3. A11 ap aratus for crimping or folding the ends 0. tubular textile fabric and for drawing a gathering or shirring thread into the criinped or folded part of said fabric, said machine comprising bars adapted to stand in a series and capable of receiving said .ubular fabric, outer crimping or folding aws, teeth on said jaws for coacting with said zigzag seriesv of bars, means for moving said outer jaws towards and away from said bars, and means for passing binding or' shirring thread through the crimped or folded part of said fabric.

4. An apparatus for crimping or folding the ends of tubular textile fabric and for drawing a gathering or shirring thread into the crimped or folded part of said fabric, said machine comprising a series of bars adapted to be arranged in alme'ment for receiving said tubular fabric, means for moving said bars relatively to each other so as to form a zigzag series, outer crimping or folding jaws, teeth on said jaws for coacting with said zigzag series of bars, means for moving said outer jaws towards and away from said bars, and means for passing a binding or shirring thread through the crimped or folded part of said fabric. v

5. An apparatus for crimping or folding the ends of tubular textile fabric and for drawing a binding or shirring thread through the crimpcd or folded. part of said fabric, said apparatus comprising bars for receivinq said tubular fabric, transverse pins on said bars for supporting said tubular fabric, means for moving said bars from a straight to a zigzag series and vice versa, outer toothed jaws for coacting with said bars when the latter are in a zigzag series, means for moving said jaws towards and away from said bars, needles, a carriage .boaring said needles, means for reoiprocatiug said. carriage, hooks for inserting a thread into the eyes of said needles, and means for moving said hooks transversely to said needles.

(3. An apparatus of the class described, comprising a row of inner jaws, the alternate jaws being connected in sets, outer jaws mounted to cooperate with the inner jaws, and means for arranging the inner jaws substantially iu alinemcnt to receive a tubular body. over them and for moving the sets of inner jaws siuiullaucmlsly in opposite dircctions to arrange them in staggered relation.

7. An apparatus of the class described, comprising a row of inner jaws adapted. to occupy a staggered relation, and a pair of o' uter j aw members having the jaws theieon my hand in presence of two suhsefihing Wit- ,turanged in staggered relation with respect masses.

to the j'awsof each jaw member anti to the 1 V coperating inner jaws, theouter jaws being DALIUEL CORN 5 movable :into and out of coperative relation 'Witnesses:
